As a result, Jessica Whitney Goddard, 29, faces up to 14 years in prison when she is sentenced Oct. 8.
Goddard was driving to work around 11:30 a.m. Sept. 2, heading south on Highway 1, when her Hyundai hit two cyclists, both from Los Osos, who were traveling on the right shoulder of the road near the Main Street exit in Morro Bay.
Alan Stephens, 65, was killed in the collision. Bradley Cummins, 60, suffered major injuries.
An hour after the incident, Goddard had a blood alcohol level of 0.07, just under the legal limit of 0.08.
Typically, defendants enter not guilty pleas during their arraignment hearings, and their next court date is set. But Goddard entered guilty pleas to gross vehicular manslaughter while intoxicated and felony driving under the influence with a three-year enhancement for inflicting great bodily injury.
Her attorney, Guy Galambos, said Goddard feels awful about the accident.
Shes in tears every time I see her, he said. And its not just about herself.
Galambos said he couldnt get into the strategy behind her plea at this time.
Any time a person enters a plea, its their own decision, he said.
At sentencing, judges are often more lenient on defendants who quickly take responsibility for their actions, but they dont have to be.
Chief Deputy District Attorney Jerret Gran said its extremely unusual for a person faced with such severe crimes to plead guilty at an arraignment.
Its an early form of closure for the victim and the victims families, he said. At the same time, they obviously have a lot of grief and a mourning process.
Goddard had allegedly visited friends in Southern California the night before the crash, when she drank vodka. The next morning after taking a train back to San Luis Obispo County the alcohol was still in her system when she began driving to work in San Luis Obispo.
Goddard had a prior DUI conviction from Ventura County in 2009.
